arenavirus

 [ah-re´nah-vi″rus]
any member of a family of spherical or pleomorphic RNA viruses containing host cell–derived ribonucleoproteins, including viruses that cause lassa fever and lymphocytic choriomeningitis; the natural hosts are rodents.

A·re·na·vi·rus

(ă'rē-nă-vī'rŭs),
A genus in the family Arenaviridae that is associated with lymphocytic choriomeningitis and several hemorrhagic fevers.

arenavirus

/are·na·vi·rus/ (ah-re´nah-vi″rus) any virus of the family Arenaviridae.

Arenavirus

/Are·na·vi·rus/ (ah-re´nah-vi″rus) arenaviruses; a genus of viruses of the family Arenaviridae that includes lymphocytic choriomeningitic (LCM) virus, Lassa virus, and viruses of the Tacaribe complex.

arenavirus

(ăr′ə-nə-vī′rəs, ə-rē′nə-, ə-rē′nə-vī′rəs)
n.
Any of a family of single-stranded RNA viruses that cause chronic infections in rodents and when transmitted to humans cause various hemorrhagic diseases, including Lassa fever.

Arenavirus

[er′inəvī′rəs]
a genus of viruses usually transmitted to humans by contact with or inhalation of aerosolized excreta of wild rodents. Individual arenaviruses are identified with specific geographic areas, such as Bolivian hemorrhagic fever in one river valley in Bolivia; Lassa fever in Nigeria, Liberia, and Sierra Leone; and Argentine hemorrhagic fever in two agricultural provinces in Argentina. Arenavirus infections are characterized by a slow onset of fever, sweats, malaise, headache, retro-orbital pain, muscle pain, rash, petechiae, hemorrhage, delirium, hypotension, and ulcers of the mouth. In rare cases in health care and family settings, some arenaviruses are associated with secondary person-to-person infection. Treatment is supportive, such as fluid and electrolyte balance, rest, and adequate nutrition. Preventative measures include rodent control. An effective live attenuated vaccine has been used in Argentina. Further trials with other vaccines are underway.

arenavirus

Any of the family of Arenaviridae of viruses which includes those causing LASSA FEVER and LYMPHOCYTIC CHORIOMENINGITIS. The name derives from the sand-like appearance of the internal granules seen on electron microscopy.

Ebola is a viral hemorrhagic fever (VHF), part of a group of illnesses that are caused by arenaviruses, filoviruses, bunyaviruses, and flaviviruses.
Molecular testing results were negative for rickettsiae, filoviruses (Marburgviruses and Ebolaviruses), selected bunyaviruses (Rift Valley fever virus, Crimean Congo hemorrhagic fever virus), arenaviruses (Lassa, Lujo, and lymphocytic choriomeningitis viruses), and several arbo-viruses (yellow fever, dengue, O'nyong-nyong, chikungunya, and Zika viruses).
Under this research grant, the arenaviruses will be selected as the primary target; however, the information gathered from these studies may extend to other viruses.
